Nathalie Kay 'Tippi' Hedren (born January 19, 1930) is an American actress and former fashion model with a career spanning six decades. She is primarily known for her roles in two Alfred Hitchcock films, The Birds and Marnie, and her extensive efforts in animal rescue at Shambala Preserve, an 80-acre (320,000 m2) wildlife habitat which she founded in 1983.

Hedren is the mother of actress Melanie Griffith, and they share credits on six films, notably Pacific Heights (1990).

Hedren was born in New Ulm, Minnesota, the daughter of Dorothea Henrietta (née Eckhardt) and Bernard Carl Hedren. Her paternal grandparents were immigrants from Sweden, and her maternal ancestry was German and Norwegian. Her father ran a small general store in the small town of Lafayette, Minnesota and gave her the moniker "Tippi". "My father thought Nathalie was a little bit much for a brand new baby", Hedren explained at a 2004 screening of The Birds. In the screen test found in the DVD extras, she explains that it is "a Swedish nickname, (short) for Tupsa... meaning 'Little Girl' in a specific Swedish dialect" (not found in dictionary).
